Hey there,
NooB here.
I have a four-year-old GE JNM3163RJSS that suddenly stopped heating and the tray stopped turning. Did some research and seemed it may be a door switch issue. Opened it and found the top door switch stuck to the wire harness and the wires harness appears damaged/burnt. The switch seems to be functioning after testing.
Ideas? fix or junk?
Thanks!
